Hanging rocks scale or fail?

A possible way of avoiding scaling as a mining task which is after all largely non-productive is to improve the accuracy of drilling and blasting so that hanging rocks do not remain after a blast In mining accurate blasting is not often as important as it in 'civils' tunnelling but this approach may benefit for permanent development and transport drives
